The shape of the plastic bottle design points

The shape of the plastic bottles to the upper, middle and bottom design into a new shape. The upper body assumes the circular, threaded cylindrical bottle, Cylindrical bottle in the middle will increase some regular patterns of stripes and other shapes, added to the bottle not only beautiful, also increased the strength of the bottle; Usually, the bottom of the bottle is concave, and has a structure similar to the dome of the petals. The design of the main consideration is to improve the bearing capacity of the bottle. Pressure stress of the plastic bottle manufacturer will force transfer to the adjacent area, the external force spread along the body surface, so that each section of the arch will share part of the force. Upper part of the plastic dome shape can be treated as a combination of several arch, can withstand external pressure and does not produce outward force. Central is the thinnest part of the bottle, when a force to sag. In order to improve the compressive strength of the middle section capacity, increase the variety of concave and convex stripes, the bottle surface rather than increase the wall thickness. The bottom of the bottle is not only a support role, but also need to often contact foreign body, which requires higher impact strength and friction. Some carbonate contains a lot of gas, and there is a certain pressure in the bottles. Bottom concave design can make the packaging bottles of stable state of upright, also can effectively reduce the risk of scratches bottle. At the same time, it can also give it the strength of the resistance to internal pressure and hydraulic pressure shock, prevent craze of the bottom of the bottle. In theory, the crack is the structure of the round bottle design, but it needs to be equipped with a can make the bottle upright and stable base. Petal shaped bottle does not need extra base, more support to ensure the stability of the bottles stand.
